During the endless shows, presentations and parties that blur into one big fashion mirage during Fashion Week, there is always one moment that blows your socks off. Everyone disagrees about what that moment is, this is not banking and it can't be defined by numbers.

For example, I've never understood the cult-like following of Marc Jacobs, he leaves me cold - and in the cold as far as my fashion peers are concerned. But every season, the fashion pack goes dotty about Marc. Prabal Gurung this week was, apparently, 'the moment' for fashion editors and stylists.

But turn off all the lights at The Armory - a 55,000 square foot drill hall built after President Lincoln's call for troops in 1861, install 10 huge screens playing on repeat Steven Klein's unsettling, dark and twisted black-and-white film installation and you've got my attention.

For starters, Klein rarely gives interviews. Little wonder: his work explores sado-masochism, bondage and sexual oppression. He once became enamoured with the idea of plaster casts, and put a cast on Justin Timberlake for a photo shoot. He also directed Lady Gaga's Alejandro video which had an army of pale mannequin men advancing like alien soldiers, all in bondage gear. What that has to do with a song about summer love affairs, I am not sure. He now has a feature film in the works.

He had to be wooed and cajoled into talking to
The Telegraph
about why he filmed Amber Valletta, old and wrinkled, wearing a gas mask sitting in a wheel chair for the sake of "art".

Carine Roitfeld found the work so disturbing she was perusing the bar for Stolichnaya. She needed a shot, she said. The ten films were accompanied by a relentless booming white noise, and a smidgeon of dry ice billowed about the room (not that anyone could see anything in the dark). Valetta, in each of the ten decades of her life, played out her role on the JumboTrons above.

Klein shot everything on a "Red" digital camera that can shoot stills and create film at the same time. New technology, he said. "It is the story of a woman; a woman reflecting forwards and backwards in time. She ages in a non surgical way," Klein told me. "This is the character: I chose to put her in one room so you could see her metamorphosis, without seeing the room change. This is the journey of a woman."
